Phenomenology of Electroweak Symmetry Breaking, Supersymmetry, and the Frontiers of the Standard Model

该奖项资助北伊利诺伊大学斯蒂芬·P·马丁教授的研究活动。这些研究活动将促进我们对宇宙的基本组成部分如何相互作用的了解。这包括对已知的基本亚原子粒子的研究，包括最近发现的希格斯玻色子。马丁还将研究超越已知亚原子粒子的新理论，包括一种被称为超对称性的可能性。超对称性的关键预测是，对于每一种已知的基本粒子类型，一定会有另一种类型的粒子具有非常相似的性质，但比目前已知的粒子重得多。马丁将致力于在实验中发现这些新粒子的策略。马丁将指导本科生和研究生的研究方法，参与高中教师的教育和培训，并通过当地和地区的科学公平评判直接与大学预科学生互动。拟议的研究将研究在对撞机上测量的可观测量与标准模型潜在参数之间的关系，通过比以往任何时候都更准确和详细的近似执行相关计算。这些计算，加上大型强子对撞机将获得的更准确的希格斯玻色子数据，将使我们能够了解希格斯场的动力学，并测试粒子物理最小标准模型的一致性。马丁将研究和改进将希格斯玻色子质量与其自身相互作用强度以及与其他粒子相互作用联系起来的公式。马丁还将继续研究超对称性，目前超对称性受到大型强子对撞机数据的显著限制，但肯定不会被排除。马丁将致力于研究最大限度地扩大大型强子对撞机对超对称粒子的实验覆盖范围的策略，方法是研究新的特征和参数空间中发现或排除特别困难或微妙的区域。他还计划研究最小超对称理论的变体，这些理论做出了独特的预测，如果发现超对称粒子，这些预测可以进行实验测试。马丁将开发更准确的计算和工具，通过将新粒子的质量和相互作用与基本理论的参数联系起来，帮助解释和理解未来的超对称性发现。这项研究将影响欧洲核子研究中心大型强子对撞机质子-质子对撞机实验的解释，以及各种暗物质探测实验。这些实验是重要的科学基础设施，在各种科学和工程领域雇用了许多各级研究人员和学生。

This award funds the research activities of Professor Stephen P. Martin at Northern Illinois University. These research activities will advance our knowledge of how the basic building blocks of the universe interact. This includes study of the known fundamental subatomic particles, including the recently discovered Higgs boson. Martin will also investigate new theories that go beyond the known sub-atomic particles, including a possibility known as supersymmetry. The key prediction of supersymmetry is that for each of the known fundamental particle types, there must be a another type with very similar properties but much heavier particles than the presently known ones. Martin will work on strategies for discovering these new particles in experiments. Martin will mentor students at both the undergraduate and graduate levels on research methods, participate in education and training of high school teachers, and directly interact with pre-college students through local and regional science fair judging.The proposed research will study the relations between observable quantities measured at colliders and the underlying parameters of the Standard Model, by performing relevant calculations in a more accurate and detailed approximation than ever before. These calculations, together with more accurate data on the Higgs boson that will be obtained by the Large Hadron Collider, will allow us to understand the dynamics of the Higgs field, and test the consistency of the minimal Standard Model of particle physics. Martin will study and improve formulas relating the Higgs boson mass to its self-interaction strength and its interactions with other particles. Martin will also continue to study supersymmetry, which now is significantly constrained, but certainly not ruled out, by Large Hadron Collider data. Martin will work on strategies for maximizing the experimental reach of the Large Hadron Collider for supersymmetric particles, by investigating novel signatures and areas of parameter space where discovery or exclusion will be particularly difficult or subtle. He also plans to investigate variations of the minimal supersymmetric theory that make distinctive predictions that can be experimentally tested if supersymmetric particles are discovered. Martin will develop more accurate calculations and tools that will aid in the interpretation and understanding of a future discovery of supersymmetry, by relating the masses and interactions of the new particles to the parameters of the underlying theory. This research will affect the interpretation of experiments at the CERN LHC proton-proton collider, and various dark matter detection experiments. These experiments are major science infrastructures, and employ many researchers and students at all levels in a variety of science and engineering fields.
